[0019] The technical solution of the present invention will be further specifically described below through embodiments in conjunction with the accompanying drawings.

[0020] A device for LED module production and testing includes a workbench 1. On both sides of the top of the workbench 1, a limiting mechanism 2 is provided. On one side of the rear end of the limiting mechanism 2, a fixing plate 3 is provided, and on one side of the front end of the limiting mechanism 2, a mounting plate 4 is provided. On the front side of the mounting plate 4, an electric push rod 5 is provided. On the output shaft of the electric push rod 5, a pressing plate 6 is provided, and the two pressing plates 6 are connected by a connecting mechanism 7.

[0021] The limiting mechanism 2 includes a U-shaped rod 21 buckled on the rear end of the workbench 1. One end of the U-shaped rod 21 is provided with a clamping plate 22 above the workbench 1, and the other end of the U-shaped rod 21 is provided with a convex seat 23 below the workbench 1. Below the workbench 1, a positive and negative lead screw 24 passing through the screw hole on the convex seat 23 is also provided, and the positive and negative lead screw 24 is driven by a motor 25.

[0022] The connecting mechanism 7 includes a Z-shaped baffle 71 fixed to the end of the corresponding pressing plate 6 by bolts. Between the two baffles 71, a connecting rod 72 is provided. One end of the baffle 71 is provided with a sliding channel 73 for accommodating the end of the connecting rod 72. In the sliding channel 73, a spring 74 connected to the connecting rod 72 is provided. On one side wall of the baffle 71, a sliding opening 75 communicating with the sliding channel 73 is also provided, and on one side of the end of the connecting rod 72, a convex block 76 passing through the corresponding sliding opening 75 is provided.

[0023] As Figure 1 shown, one horizontal end of the baffle 71 is buckled on the front side wall of the pressing plate 6 and fixedly connected by bolts, and the other horizontal end of the baffle 71 forms a straight line with the pressing plate 6.

[0024] As Figure 1 shown, the fixing plate 3, the mounting plate 4 and the pressing plate 6 are all located between the two clamping plates 22, and the fixing plate 3 and the mounting plate 4 are fixedly connected to one side wall of the clamping plates 22.

[0025] In this embodiment, fixing seats 8 for fixing both ends of the positive and negative lead screw 24 are provided at the bottom of the workbench 1. On the fixing seats 8, rolling bearings for fixing the positive and negative lead screw 24 are provided, and the positive and negative lead screw 24 is screwed with the screw hole on the convex seat 23.

[0026] As Figure 2 shown, a chute 9 with an isosceles trapezoid cross-section is provided along the length direction on the rear side wall of the workbench 1. The upper bottom end of the chute 9 communicates with the outside of the workbench 1, and a sliding seat 10 adapted to it is provided in the chute 9. The sliding seat 10 is fixedly connected to the vertical end of the U-shaped rod 21 by bolts.

[0027] Working principle of the present invention: Adjust the distance between two sets of limiting mechanisms 2 according to the length of the module. The specific steps are as follows: The motor 25 drives the forward and reverse screw rod 24 to rotate in the screw holes of two sets of convex seats 23, and then drives two sets of convex seats 23 to slide to expand or reduce the distance between two sets of convex seats 23. At this time, the convex seat 23 drives the clamping plate 22 to move through the U-shaped rod 21, and then expands or reduces the distance between two sets of clamping plates 22, so that the distance meets the production requirements;

[0028] When the U-shaped rod 21 moves, it will drive the sliding seat 10 to slide in the sliding groove 9, so as to fix the U-shaped rod 21 while facilitating its movement. When the clamping plate 22 moves, it will drive the corresponding fixing plate 3, mounting plate 4 and pressing plate 6 to move. After the position of the clamping plate 22 is adjusted, the product is placed between two sets of clamping plates 22, and its rear side abuts against the front end faces of two sets of fixing plates 3. At this time, the electric push rod 5 drives the pressing plate 6 to move backward and abut against the front end face of the product, so as to fix the product through two sets of clamping plates 22, fixing plates 3, pressing plates 6 and baffle plates 71, preventing it from moving horizontally during processing, and there is no need to open holes on the workbench like the prior art, so as not to affect the subsequent production work of the workbench for other different types of products.

[0029] As Figure 1 shown, the contact area with the front end face of the product is increased through the baffle plate 71 on the connecting mechanism 7 to improve the clamping stability of the product. When the baffle plate 71 moves towards the connecting rod 72, it will compress the spring 74 and drive the sliding opening 75 to slide on the convex block 76 to reduce the distance between two sets of baffle plates 71, preventing it from affecting the movement of two sets of limiting mechanisms 2. Similarly, in order to increase the contact area of the device with the rear side of the product and not affect the change of the distance between two sets of limiting mechanisms 2, a connecting mechanism 7 can also be provided between two sets of fixing plates 3 to solve this problem.

[0030] The above has described the present invention in detail, but the content described is only the preferred embodiment of the present invention and cannot be considered as used to limit the scope of implementation of the present invention. All equivalent changes and improvements made according to the scope of the application of the present invention should still fall within the scope covered by the patent of the present invention.
